-dust remaining.

In order to give the fan motion, I attachrto the lower side of the cone, upon shaft D, a'. spur gearwheel, r', whichgears into pinion r', on sha'tt; s.

.Upon the lower end is wheel t, gearing into pinion t', on thearbor of the fan, which arrangement gives the desired motion to the fan,

'lhe parts thus constructed and placed together, as seenpin g. 1, the rice or other grainpnt in'hopper l), motion is given to the `cone C, the kernels withthe husk on them pass between the cone and shell, and while in such passage, the action of the seria-ted unyielding surface of the shell with the yielding surface of the cone completely takes oit' all covering from the grains of rice, leaving such grains whole and rveady to be polished, 'and as they pass lower down come" in contact with the yielding surface of the shell and cone, and are there subject to so delicate a frictionbetween `the two yielding surfaces, as to completeiy eradicate all particles ot' thcinner coating of the grains, or of any \Vhen the grain falls from between the cone and shell, it comes in contact with the blast of air created by thel rapid revolutions of the fan, where all the husk and 'dust are .sent away, and the clean, whole grains of rice fall into thc proper receptacle, it for packing for market.

I am aware that rubber, leather, 'sheep-skins, and other yielding substances have been used in hulling and polishing rice and other grains; but I am not aware that any elastic surfaces, such as I have described, have ever been used for such purpose.

I do not wish to confine myself in my claim to the use of such construction of cone as I have described for hulliug rice or other grains, as it may be used for various other purposes where an elastic surface is peeded, as upon rollers having parallel sides and yield mg surfaces, or where they have an irregular or other form, the invention is the same.

Having thus described my, invention,

XVh-at I claim, and desire to secure by Letters Patent, isl l. The cone or roller C, herein described, when constructedwith yielding surfaces ot' thin metal plates, (l, or their equivalent, set edgewise,l arranged and applied as described, and resting upon or against a rubber bed, in the manner and for the purpose substantially as herein set forth.

2. The cone or roller C, herein described, when constructed with a yielding surface of rubber' and cloth, or leather, set edgewise, substantially as and for the purpose herein set'forth.

3. "lhe cone or roller C, herein described, with a yielding surface of lmetal pins passing through a perforated metal plate,.a nd resting 'upon or against a rubber bed, substantiallyas and for the purposes herein set forth. p f

4. The oomliination of the cone C, herein described, with the shell lA; having an unyielding serrated surface, a, and yielding surfaces H, and brush I, constructed in the manner and for the purpose substantially as herein set forth.

The fan Gr, constructed of plates of thin sheetmetal, having slots through them, forming, when bent, moitises and corresponding tenons, and held together by a pin or arbor, substantially as herein setl forth.
